There's a reason they dropped the Favored Enemy mechanic, and it's the same reason they dropped the "Rogue can't Sneak Attack the Undead or Constructs" mechanic from previous editions: it's not fun for players to say "well, maybe I'll get to do the cool defining feature of my class tomorrow." It feels especially unfair when spellcasters get to do cool stuff pretty much no matter what.
